'IMPROVEMENT IN SAND-CHAMBERS FOR WELL-PUMPS.

Specilicaton forming part of Letters Patent No. 98,503, dated January 4,1870; antedaled December 24, 1859.

To all whom` it may concern:

Be it known that I, EDWARD C. JOHNSON, ofthecityot'Williamsport,countyot'Lycoming, and State of Pennsylvania., have invented a 'f ncwand improved inodeof preventingthe sand o from passing into Wel1-pumps from the tube lo ence marked thereon.

The nature of my invention consists iu providing a sand'chamber and in placing a screen in said chamber, so as to prevent the sand from Y passing to the pump valve, and alsoin providing means for the easy removal of the sand when it shall havecollectrd in said chamber. To enable others skilled in the art to make and use my invention,I will proceed to describe its construction and operation.

I rst cast thecap a, havingaplugged opening, Bf, and projection or tube, by means of which it can be attached to the pump, and also having the proper holes, through which bolts C C O C are passed, having nuts to fasten and hold said cap to the chamber G, which chamber is cast with a proper tube, F, extending' below the chamber G, to serve as an attachf ment to the pipe coming from the Well or cis tern. At the upper end of the tube F, I place the cover E,lhaving its supports H H H H,` which supports are narrow, and. thus leaving the proper openings for the passage of the water when the pump is operated. Over the top of the chamber G, I place the screen D, made of wire-gauze, having the meshes oropenings ot' the proper size. Said chamber G is provided with a plugged opening, B2, at its lower point, and about in line with plugged opening B. Now, to the cover ct, I attach the pump, and it will be seen at ay glance, when the pump is operated, that `the water Will pass through the openings between the support-s H H H H, and the sand, being ofgreatergravity than the water, will fall to the bottom of the chamber G, and the screen D will not allow it t0 pass to the valve of the pump. So, When the chamber Gr is llled withv sand, I have simply to remove the plugged openings B and B2 and a stream of water will drive the sand from the chamberG when poured into plugged opening B', while plugged opening B2 is removed.

Having described myinvention, what I claim as my invention, and desire to procure by Letters Patent, is

1. The combination, with the sand-chamber, ofthe inlet-pipe F, haying arcover, E, and the screen D, as and for the purpose set forth.

2. In combination With the above, the plugged openings B B2 for removing the sand from said chamber, as described.
